Solution
Change settings in your computer BIOS setup utility.
If your computer has the options of enabling Plug-and-Play detection, or assigning an IRQ
to a VGA adapter, make sure they’re enabled. If your computer doesn’t have these options,
you may be able to manually assign an IRQ to your graphics card using the BIOS setup utility.
For more information on the BIOS setup utility of your computer, see your system manual
or contact your system manufacturer.

Cause
Your computer’s other BIOS settings may be incorrect.
1
Solution
Reset your computer BIOS settings to the factory defaults using your computer’s built-in
BIOS setup utility. The factory defaults are usually the “safest” settings. Check your system
manual for more information.
